Major Power Technology Co., Ltd. Rev.1.6 Nov 13, 201 7 Single Output Hall Effect Latch GENERAL DESCRIPTION MA7020/B is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device is using HV BCD process includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal band-gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. If a magnetic flux density larger than threshold Bop, OUT is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned off (high). FEATURES - 2.5V to 26V DC operation voltage - Temperature compensation - Wide operating voltage range - Open-Drain pre-driver - 25mA maximum sinking output current. - Low Profile TSOT/SOT23-3L and SIP-3L(TO-92S) Package( Green and Lead Free ) PIN ASSIGNMENT The package of MA7020/B , the pin assignment is given by: VDD OUT (Top View) GND VDD GND OUT (Top View) MA7020 SIP-3L MA7020/B TSOT/SOT23-3L Name Description VDD Supply Voltage OUT Output GND Ground.
